Emmerson Mnangagwa is a politician and former vice president of Zimbabwe. Mnangagwa, born September 15, 1946, is nicknamed "Ngwena," or "The Crocodile."

In 1963, soon after modern Zimbabwe's ruling party ZANU-PF was formed, Mnangagwa was part of the first group of young party leaders sent to China for military training. Upon his return, he earned his nickname by leading a group of fighters called the Crocodile Gang during the country's war of independence against Rhodesia's white-minority rule.

Mnangagwa's gang blew up several trains. He was arrested in 1965 and sentenced to death. He escaped that fate because his lawyers successfully argued that he was under 21 and hence underage for the hangman's noose. But he was brutally tortured and spent 10 years in jail, where he met and befriended Robert Mugabe.

Mnangagwa was released after serving his sentence and deported to Zambia, where he studied law. He kept in close contact with Mugabe and was elected special assistant to Mugabe in 1977, becoming head of both the civil and military divisions of ZANU-PF.

When Mnangagwa lost a parliamentary election in 2000, Mugabe appointed him to one of the unelected seats in parliament, and he was then elected speaker.

In 2008, he was credited with masterminding Mugabe's presidential campaign. Opposition leader Morgan Tsvangirai won the first round of the election. Hundreds of opposition supporters were killed in a campaign of violence blamed on the military and state security organizations.

Tsvangirai pulled out of the second round of elections. Mugabe was re-elected, and Mnangagwa became defense minister.

After Mugabe won another presidential term in 2013, Mnangagwa was appointed vice president.
